<blockquote>
<p> 等着全套的DevOps系统写完了，推荐几个平台，然后企业私有云也就有了，再也不用折腾安装时的环境了，万岁，团队也就不用我自己来做架构，做运维，做DevOps，做监控，做管理，做培训~~</p>
<p> 越写越感觉现在技术的进步性，越想着做业务，做管理….</p>

<p>一般情况下推荐使用Dockerfile进行镜像构建，实在太懒。。。那么就pull官方镜像安装吧。本文是以Dokcerfile安装的Mysql8。</p>

<h2 id="制作镜像并运行容器"><a href="#制作镜像并运行容器" class="headerlink" title="制作镜像并运行容器"></a>制作镜像并运行容器</h2><ol>
<li><p>制作镜像 <code>docker build -t mysql:v8</code> </p>
</li>
<li><p>运行镜像 <code>docker run -d -p 3306:3306 --name mysql -v $PWD/config:/etc/mysql/conf.d -v $PWD/logs:/etc/log/mysql -v $PWD/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=pl,okm mysql:v8</code></p>
</li>
<li><p>进入容器给root用户远程访问权限，说明mysql8与前面的版本赋权稍有不同，以下命令8中不能使用</p>
<p><del><code>Grant all privileges on *.* to‘someBody’@’SomeIP’identified by‘somePassword’[with grant option];</code></del>  </p>
<p>正确的方式是： <a href="https://dev.mysql.com/doc/refman/8.0/en/adding-users.html" target="_blank" rel="external">官方说明</a></p>
<p>首先赋权是先创建用户，然后给用户赋权，用户的密码加密方式改变想改回原来的密码方式需要加指定参数，否则工具链接的时候会提示错误1251。</p>
<ul>
<li><p>创建用户 ：<code>CREATE USER &#39;root&#39;@&#39;%&#39; IDENTIFIED BY &#39;password&#39;;</code> </p>
</li>
<li><p>用户赋权：<code>grant all privileges on *.* to root@&#39;%&#39;;</code></p>
</li>
<li><p>修改密码加密方式：</p>
<p><code>ALTER USER &#39;root&#39;@&#39;localhost&#39; IDENTIFIED BY &#39;password&#39; PASSWORD EXPIRE NEVER;</code></p>
<p><code>ALTER USER &#39;root&#39;@&#39;%&#39; IDENTIFIED WITH mysql_native_password BY &#39;password&#39;;</code></p>
<p><code>flush privileges;</code></p>
</li>
<li><p>然后使用远程工具就可以链接上了，同时查看一下mysql/data中的已经进入数据。</p>
</li>
</ul>
</li>
</ol>
<h2 id="一些简短说明"><a href="#一些简短说明" class="headerlink" title="一些简短说明"></a>一些简短说明</h2><ol>
<li><p>下载的文件中有<code>.sh</code>脚本文件，要先赋予权限 <code>chmod +x</code>在执行构建镜像，记的前面打章节中说明了，根据<code>Dockerfile</code>构建镜像会把当前目录所有的文件包括权限制作进镜像中。如果你出现以下问题，请删除镜像重新制作。</p>
<p>异常信息：<code>docker: Error response from daemon: OCI runtime create failed: container_linux.go:348: starting container process caused &quot;exec: \&quot;docker-entrypoint.sh\&quot;: executable file not found in $PATH&quot;: unknown.</code></p>
</li>
<li><p>镜像中的时区问题不是国内时区，执行如下命令即可<code>cp /usr/share/zoneinfo/PRC /etc/localtime</code></p>
</li>
<li><p>mysql镜像中存储说明<img src="https://ws1.sinaimg.cn/large/005SYMRrly1ftsas3075gj30qw082dgp.jpg" alt=""></p>
</li>
<li><p>删除正在运行的容器，只要不删除宿主的目录，再重新执行创建命令，创建后原来的数据还是存在的。</p>
</li>
